Introduction

When dealing with fractions that contain variables, simplifying them can be a crucial step in solving mathematical problems. In this article, we will focus on simplifying the expression $\frac{y^6}{y^2}$ , which involves applying the rules of exponents and understanding the properties of fractions.

Understanding Exponents

Before we dive into simplifying the expression, it's essential to understand the concept of exponents. An exponent is a small number that is written above and to the right of another number, which is called the base. The exponent indicates how many times the base should be multiplied by itself. For example, $y^2$ means $y$ multiplied by itself twice, or $y \times y$ .

Simplifying the Expression

To simplify the expression $\frac{y^6}{y^2}$ , we need to apply the rule of dividing exponents with the same base. This rule states that when we divide two numbers with the same base, we subtract the exponents. In this case, we have:

\frac{y^6}{y^2} = y^{6-2} = y^4

Explanation of the Simplification Process

Let's break down the simplification process step by step:

Identify the base: The base of the expression is $y$ .
Identify the exponents: The exponents are $6$ and $2$ .
Apply the rule of dividing exponents: Since the base is the same, we subtract the exponents: $6-2 = 4$ .
Simplify the expression: The simplified expression is $y^4$ .
